RESILIENT WHEEL.

vApplication filed March 13, 1913. Serial N o'. 754,111.

To all 'whom t may concern Be it known that l, BENJAMIN J. COBB, citizen of the United States, residing at Rome, in the county of Floyd and State of Georgia, have invented certain new and useful Improvements in Resilient Wheels, of which the following is a specification.

This invention relates to an improvement in resilient wheels.

The primary object of the present invention is to provide a wheel for trucks and the like which will have the same resiliency as the rubber tired wheels now in use, and which will not be subject to the many disadvantages of cushion tired or pneumatic tired wheels.

A further object of the invention is to provide .a mechanism which, while suihciently resilient, will be substantial and in which the spring cushioning means will not be distorted or disarranged when a heavy load is applied or when the wheel meets with an obstruction.

For a full understanding of the invention, reference is to be had to the following d escription and accompanying drawing, in which:

Figure 1 is a side elevation; Fig. 2 is a sectional view of a portion of the wheel; Fig. 3 is a transverse section.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

The wheel consists of spaced inner and outer rims. The inner rim 10 is supported by the spokes 11 which are secured to the hub 12. This inner rim intermediate the spokes is provided with openings 13, and secured to the rim and surrounding the openings are housings 14, the housings being disposed on the inner face ofthe rim. A plurality of plates 15 and 16 are secured tothe rim 10 by means of bolts 17 thereby forming a channeled rim or felly. The periphery of the rim isprovided at intervals, and preferably at points in alinement with the spokes, with sockets in which are seated coiled springs 18.

The outer rim 19 is provided with any suitable form of anti-skid construction, and secured to said rim are plates 20 which embrace the plates 15, the two sets of plates sliding with respect to each other as the hub becomes eccentric to the Outer rim. The inner face of the rim 19 is provided with sockets 21 which aline with the sockets 17 formed on the periphery of the linner rim, the springs 18 in this manner being supported against displacement.

A plurality of guide rods or plungers 22 are supported by the outer rim throughout its entire circumference, said guide rods eX- tending through the openings 13 formed in the inner rim being received by the housings 14:. These guide rods are maintained against displacement by nuts 23 which are threaded on the same adjacent their terminals, the Outer rim being clamped between said nuts and the heads 24 of the rods.

The openings 13 in the inner rim are suiiiciently large to allow for a certain amount of'movement of the rods. It will be noted, however, that the rims are maintained prop.- erly assembled by means of these rods, and that while they may participate in the necessary movement to sufficiently cushion the aXle, the springs will not be distorted or displaced by the pressure of the load or the contact of the wheel with an Obstruction.

It will also be seen that the mechanism is elfectually housed, and that foreign matter will not enter between the rimsto aifect their cushioning movement.

Particular attention is called to the fact that the entire structure may be easily vand economically manufactured, and that the various parts may be readily assembled.

Attention is called to the fact that the heads 24C of the rods extend beyond the outer rim and yform effectual anti-skidding devices. of the springs may bey connected with the studs 18', thereby preventing the displacement' of said studs, the studs either being formed integral with the terminals of ythe It will also be seen that the terminals springs or secured thereto in any suitable ject radially beyond the outer face of the of spokes, and a housing secured to the in- 10 outer rim, radially disposed guide rods sener face of the inner rim and inelosing the Cured to the outer rim and extending inner extremity of each of said rods.

through the inner rim, the inner rim having In testimony whereof I affix my signature apertures formed therein to loosely receive in presence of tWo Witnesses.

said rods, said rods also being provided With BENJAMIN J. COBB. [1.. s] heads arranged to project radially beyond Witnesses:

the outer face of the outer rim and one of C. A. THORNWELL,

said rods being disposed between each pair SAM JOHNSTON.
